• Russia expresses readiness to restart arms-control talks with the United States, but no formal agreement or schedule is in place.
  • The development follows the February 2026 expiry of New START, leaving the world's two largest nuclear powers without binding limits on strategic arsenals for the first time since 1972.
  • Key obstacles remain, including U.S. insistence on including China and ongoing tensions over Ukraine.

Diplomatic Overture

Russia has signaled a willingness to resume arms-control dialogue with the United States, according to Kremlin spokesman Dmitry Peskov, who said on September 28 that talks should have restarted "yesterday." However, Peskov cautioned that any negotiations would require lengthy, technically detailed expert discussions, indicating that a breakthrough is not imminent.

The statement follows discussions between U.S. and Russian negotiators in Abu Dhabi in early February, where both sides acknowledged the need to begin arms-control talks quickly. At that time, they also agreed to restore high-level military-to-military dialogue, which had been suspended amid deteriorating relations before Russia's 2022 invasion of Ukraine.

No Binding Limits

The urgency stems from the February 5, 2026, expiry of New START, the last bilateral treaty capping the two countries' deployed strategic nuclear forces. The treaty, signed in 2010, limited each side to 1,550 deployed strategic warheads and 700 deployed delivery vehicles, and included a verification system with data exchanges and on-site inspections.

However, inspections stopped during the COVID-19 pandemic and never resumed. In February 2023, Putin suspended Russia's participation, citing the Ukraine war and U.S./NATO support for Ukraine, though Russia said it would observe numerical caps. Putin later proposed voluntarily continuing New START limits for one year, but the U.S. did not accept a formal extension, emphasizing that a new agreement should account for China's expanding arsenal.

The treaty's expiration marks the first period since 1972 in which the United States and Russia have no binding bilateral limits on strategic nuclear arsenals.

Scope Dispute

The principal obstacle to a new agreement remains scope. Washington has pushed for a future arrangement that includes China, but Beijing continues to reject participation, arguing that its nuclear arsenal is much smaller than those of the United States and Russia. Moscow says China's stated position has not changed.

The broader U.S.-Russia relationship remains constrained by the war in Ukraine. According to Reuters, Moscow seeks a broader restoration of ties, but Ukraine-related differences have prevented a meaningful reset. The Kremlin's desire for a reset was underscored by a meeting between Putin envoy Kirill Dmitriev and U.S. officials in Washington on September 29 to discuss Ukraine and potential postwar U.S.-Russia energy initiatives. That does not establish a deal, but it indicates that arms control is unfolding alongside wider—still highly tentative—contacts on the war and postwar economic relations.

Economic and Security Implications

The most direct economic implications arise through defense spending, security risk, and geopolitical uncertainty rather than trade flows. Without verifiable caps, both governments could decide to upload additional warheads to existing delivery systems or expand nuclear-force modernization. Whether they actually do so will depend on security conditions, domestic budgets, and competing military priorities—not solely on the treaty's expiration.

For the United States, a less constrained nuclear environment may reinforce demand for nuclear-triad modernization, missile defense, early-warning systems, submarines, strategic bombers, and related aerospace and defense supply chains. That can support defense-sector orders, but it also intensifies fiscal tradeoffs against civilian priorities. Russia faces a different constraint set: sustaining its war effort, managing sanctions-related pressures, and funding strategic-force modernization simultaneously. A negotiated framework could reduce the need for the most expensive forms of reciprocal nuclear buildup; a prolonged breakdown could encourage additional spending and planning uncertainty.

The market effect is primarily a risk-premium story. Heightened nuclear confrontation can raise geopolitical-risk premiums across European assets, energy markets, defense companies, sovereign debt, and insurance, even when there is no immediate change in weapons deployment.

International Reaction

UN Secretary-General António Guterres warned this week that the world is in its most dangerous nuclear moment since the Cold War's end, citing nuclear modernization, growing arsenals, and a heightened risk of accident or miscalculation. He urged Washington and Moscow to negotiate a successor to New START and called for the Comprehensive Nuclear-Test-Ban Treaty to enter into force.

The UN discussion highlighted that global inventories exceed 12,000 nuclear warheads and that roughly 2,100–2,200 are maintained on high operational alert, underscoring why crisis communication and predictable force postures matter. NATO allies and European governments are likely to view any U.S.-Russia dialogue through the lens of Ukraine and regional security. A narrowly nuclear agreement could reduce strategic risk, but it would not resolve Russia's war against Ukraine, conventional-force threats, or disputes over European security architecture.

China is a decisive stakeholder even if it remains outside negotiations. Its refusal to enter trilateral negotiations is one reason a broad replacement treaty is difficult to construct; conversely, insisting on Chinese participation as a precondition could delay bilateral U.S.-Russia limits.

Outlook

The headline is constructive rhetoric, but the material test is whether it leads to formal agendas, negotiating teams, reciprocal interim restraints, and verifiable commitments. Until then, the post–New START environment remains one of dialogue interest without restored nuclear guardrails.

In the short term, the most realistic outcome is exploratory expert dialogue, potentially paired with military-to-military risk-reduction contacts. A legally binding comprehensive treaty appears unlikely quickly, exactly as Peskov indicated.

In the medium term, a politically feasible interim arrangement could involve voluntary reciprocal restraints, renewed notifications or transparency measures, a commitment not to exceed certain New START-era ceilings, or limited verification mechanisms. Such measures would be less robust than a treaty but could slow an unconstrained buildup.

In the long term, three broad paths are plausible: a successor bilateral treaty that restores ceilings and verification; an interim political understanding that reduces near-term risk but remains vulnerable to policy reversals; or no durable agreement, which encourages force modernization, hedging against worst-case scenarios, more opaque deployments, and a wider three-way competition involving the United States, Russia, and China.
